I am trying to repurpose a treadmill motor and motor controller on a treadmill with a trashed console unit. The controller is identified as an ICON MC1684DLS ZE0824. The motor itself seems fine running on a battery but I am needing some help with the wiring of the controller board. A photo of the board is attached along with a couple of zoomed in images.

I am trying to identify the 9 wires going to the (10 pin) connector. The wires go to the console. I don't see any identification on the board itself and if I look at the board on the console all it says is "treadmill". Gee that is a big help, ha ha.

I am assuming the red and black are power but I have no idea what the other wires do. Does the UPT and DS mean anything to anyone? There are 2 VG on the other side.

My thinking is that if I can identify the wire's purpose then I and produce the signals using an Arduino or some other method to create PWM or other signals as needed. I would just love to see a schematic with the connections identified but have been unable to find one on the internet.

Connector at the console


Any help would be greatly appreciated.

 

I have some knowledge of the MC2100 series but none on this one, I'm afraid.
But if similar, the board DC supplies are on the main board typically it has a 12v DC supply for the console where the second processor is located.
To run as a separate unit, all that is required for the MC2100 is a 50Hz PWM signal.
This signal enters the board through a 4-pin opto-isolator 817, etc.
The red & blk would typically be the supply for the console.
Some tests of the 10pin connector may reveal something.
Together with a little reverse-engineering.
Blue is the PWM signal on the other version.

 

I will be on the lookoutto see if I can pick one up for reverse-engineering, maybe do a swap for a working MC2100 ! ?

Thanks, I have figured out a little bit but not a whole lot. The U and D pins are for the incline motor up and down and I got that working ok.
There are 2 reds (one striped) with 12 volts and 2 blacks (one striped) that are ground. (marked V and G)
That leaves P, T, and S pins.
I was thinking P might be for PWM. I tried putting 12 volts on that pin (100% duty) but nothing happened. I fiddled around with the others and still got nothing. I am wondering if one of the pins is to enable/disable the controller for safety or something.
Actually I have no clue and am not 100% sure the board works but I was told it worked before the console got broke.
I also tried tracing wires at the console but they all go into another circuit board and I can't follow anything.
The
P pin has light blue wire
T pin has green wire
S pin has purple wire
if those colors mean anything to you.

 

12v is not going to cut it, if it requires PWM. !
Is there any sign of an opto similar to what I indicated the MC2100 has?
Also, I assume the board has a processor IC on it?

Thanks for the info. I am not sure about the opto. I hope I didn't fry it with my playing around. I will continue to try and figure it out.

I'm working on this board now as well, not sure if you found your answers, from what I found T was for "tach" the speed sensor and the violet/purple wire on S was the incline sensor. supposedly either 0 or 5 VDC

Hi Jps80,
any success? i have the same issues , lost the consol when an update was launched. now before ordering a new MP10 Argon screen ,i wanted to make sure that the rest of the treadmill is functioning/ my controller board is ICON ZE0824. i can't determine the pins PST which is the pmw . and probably there is an enable some where.
i am pretty sure the board is good but it is the matter of the correct singnals to the correct pins.
thanks
